During much of the year, Texas Mountain Laurel,
Sophora secundaflora, is easily overlooked. But in March, this small accent tree is a show stopper. That's when you will find them covered with huge clusters of purple flowers.
Native to Central Texas, this member of the Pea family tends to be a multi trunked, somewhat slow growing plant. Although I've seen some larger, most Texas Mountain Laurels will grow to about 12 -15 feet. It has dark green, glossy leaves.
Native to the alkaline hills of Central Texas, this is a drought tolerant plant. It will tolerate the heavy clays of the lower Rio Grande Valley but make sure that you plant it in an area that drains well. It doesn't like wet feet. It's root structure is very sparce - with very few fibrous roots. (guess that's why it grows well in the Hill Country) This makes transplanting a little bit difficult. If you break the root ball while planting, you may lose your tree.
Oh, but what a reward this tree gives in March! The wisteria-like blooms smell like grape soda and attract bees and butterflies alike!
But beware. Most parts of this plant are poisonous - especially the claret red seeds in the seed pods. Another common name for Sophora secundaflora is Mescal Bean. Indians used the seeds as hallucinogenics - and I have read of deaths from this practice.
You can see why this tree is often overlooked when not in bloom. This one looks a little starved for nitrogen - the leaves tend to be much darker green.
Mountain Laurel is deer resistant - but the webworms love the one in my yard. My hubbie is pretty good about checking it a few times a week and squishing all the little worms that are munching on it. We have never needed to apply any chemical, but if squishing the worms is not your cup of tea, a BT product to take care of the worms.
This tree is just beginning to bloom. Mountain Laurel will produce its bloom stem many months before it's time to bloom. Some people mistakenly think they are from last years blossoms and remove them - then they wonder why their tree didn't flower!
